have to
🔒 只得 = only + get — when you only get one option, you have to take it
只 — mouth 口 + bird tail 八
Originally a pictograph showing a bird (口 as body) with its tail feathers (八) spread, meaning a single bird. It was later borrowed phonetically to write the grammatical particle and adverb meaning 'only' or 'just,' which became its dominant modern use.
得 — 彳 (step) + 旦 (sun/day) + 寸 (hand)
Originally depicted a hand 寸 reaching for a cowrie shell 貝 (later simplified to 旦), with 彳 'step' added to show going out and obtaining something. The core meaning is 'to get' or 'obtain'. The reading děi extends this to 'must/have to' — what one is obliged to get done.
